Business Operators Need To Know Rules On Handling Of Waste Items When Re-entering The Country There are strict rules for properly dealing with refuse when flying back into the United States, and experts say breaking the law risks stiff fines and even prison sentences. All garbage generated onboard business aircraft arriving from origination points outside the continental U.S. or Canada is regulated by The Animal and Plant Health Inspection Service (APHIS) of the U.S. Department of Agriculture (USDA).The primary purpose is to contain biological waste – including fruits, vegetables, meats or other plant or animal products, and any other items associated with those materials – to prevent the introduction of pests and diseases into the country. Airports, FBOs and business aircraft operators all have important roles in this process.
